Mechanical Properties

Corrosion Resistance

Duplex steel UNS S31500 has impressive properties, making it a sought-after material among multiple industries. It is known for its corrosion resistance and high strength, and toughness. This makes the alloy suitable for projects that require superior corrosion resistance, like sea water piping or marine use, chemical industry and food processing equipment. The combination of good strength, excellent corrosion resistance and high toughness, even at low temperatures, make duplex steel UNS S31500 an ideal choice for demanding applications since it provides more cost-effective solutions than other alloys.

Heat Resistance

Duplex steel UNS S31500 is known for its superior heat resistance properties compared to conventional stainless steel alloys. Due to its two-phase microstructure, the alloy shows excellent oxidation and corrosion resistance – even in harsh environments. In addition, it has a higher chromium content which helps it withstand elevated temperatures without losing ductility or toughness. This makes Duplex steel UNS S31500 an ideal choice for applications such as wall panels and linings in chemical processing units, marine equipment and pressure vessels operating at extreme temperatures.

Heat Treatment

This alloy is resistant to pitting and crevice corrosion and retains its strength when exposed to temperatures up to 600°C. To achieve these amazing performance levels, S31500 must be heat treated carefully to maintain the balance between its ferrite and austenitic structures. During heat treatment, the alloy may undergo several cycles of heating and cooling to reach the desired level of toughness and corrosion resistance. Once it has been heat treated, duplex steel UNS S31500 can be used for components that require long-term exposure to corrosive environments or extreme temperature fluctuations.
